A while ago, I found the "FuN" proposal on Area-51 and flagged it, adding a note that (IMO) it was not a real proposal. Sure enough, the proposal was closed as "Not a real proposal" shortly afterwards, so apparently other people flagged it too.

Yesterday, I flagged another proposal as a possible duplicate.

I cannot see my flag weight on Area-51, nor do I have a "Citizen Patrol" badge there. So I am led to believe that flagging proposals (as opposed to flagging example questions) on Area-51 doesn't count towards flag weight.

This is fine with me, but it makes me wonder - is there a rationale behind this?
